I am having constant problems when using span columns – especially when it is part of a paragraph style and I want to switch from span to no span or vice versa. I get the wheel of death turning turning turning. Activity monitor on Mac says 100,3% used by Indesign. Not responding. I have tried IDML trick. I am using latest version of Indesign CC on MacBook Pro 2,5ghz Intel Core i& 16GB 1600 mhz DDR3 memory. Any ideas?
I think span columns has always been a little unstable, but I've not had a lto of occasion to use it other than for headlines on newspaper stories.
Does it work better if you define, and assign, a new paragraph style instead of using an override?
